| 源码 | framework/validators/CDefaultValueValidator.php |
CDefaultValueValidator sets the attributes with the specified value.
It does not do validation but rather allows setting a default value at the
same time validation is performed. Usually this happens when calling either
$model->validate() or $model->save().公共属性
